“A loop of fun trails through the forest begging for exploration. Occasional views to the east out of the forest canopy.”
— Mark Emagin
This is a short but fun loop to explore the Las Posadas State Forest north of Napa.
Las Posadas is a research forest located in Angwin. It's composed of many criss-crossing trails through manzanita and oak, making it mostly shaded. There are some fire roads and easy drops, but nothing overly challenging. That said, expect a few technical sections and you can access more singletrack with additional challenges throughout to up the mileage.
